Abstract

In this paper the electromagnetic transients in electrical power systems are described, analyzed, and investigated. The cable-based networks are the main concern of this investigation. Several transient phenomena are described theoretically and demonstrated by means of simulations performed both in simple and complex systems. The EMPT-ATP is used for the simulation. Some of the phenomena are very unlikely to occur and have an uncertainty associated with them, while others can be predicted with a high degree of certainty. Some depend only on the cable and equipment directly attached to it, while others depend on the cable and surrounding area.
For all these reasons, one cannot immediately say which phenomena should be prioritized when performing an insulation co-ordination study. The application of the countermeasures depends on the phenomenon that must be minimized. However, some of the countermeasures intensify some phenomena while at the same time minimizing others. The energisation of cables in all its different variants; ideal energisation, energisation in weak grids, and energisation of cables in parallel are discussed. The energisation of a cable in a weak grid poses an interesting challenge, because of the high overvoltages associated to phenomenon. Another interesting analysis is the one make on the energization of cables in parallel. The de-energisation of a cable is another transient phenomenon that needs to be investigated.
